Abstract—The assimilative capacity of the Eastern region, Thailand is estimated by using ventilation coefficient data and air quality model. Box model is used to predict the spatial and temporal distribution of two pollutants namely SO
2 and NO
2. Meteorological characteristic of the study area in the year 2010 was selected in the analysis. The results indicated that Tha-Takiap, Chachaengsao was the highest assimilative capacity of SO
2 and NO
2. Temporal variation of assimilative capacity of air pollution in the study area in which the highest carrying capacity was in November.
Index Terms—Air assimilative capacity, air quality model, ventilation coefficient.
